# Black Holes: #4 Perturbing

A continuation in the series on Black Holes, examining the Black Hole Stability Conjecture. Asking whether, when black holes are disturbed they return to their stable state after spewing out gravitational waves.

A post describing Einstein-Cartan theory; an alternative to Einstein’s General Relativity which could more closely describe the universe, as well as removing some of the big problems posed by general relativity.

A post qualitatively explaining the main ideas behind the AdS/CFT correspondence. The breakthroughs in theoretical physics due to the theory are outlined along with the consequences for how we view our universe.

Today we bring together black holes and exoplanets to fantasise over the ultimate solar system with a dark twist.

A continuation in the series on Black Holes, examining the inner horizon known as the Cauchy Horizon and its implications on space and time.

How quantum fluctuations in the early universe acted as seeds of structure and eventually led to the formation of the galaxies that we see today.

Contains fairly complex ideas and references to previous posts.

An extended piece on the nature of time as a result of the theory of Special Relativity.

A brief, purely discursive, post explaining the motivations for and success of Quantum Field Theory.

Today we will present the basics of Group Theory. Group Theory is essential to theoretical physics as it examines the symmetries of nature to uncover fundamental connections and patterns within the universe.

Revisiting the theme of time we explain the geometry of spacetime and explore the special quantity known as ‘proper time’. A qualitative post which includes the use of simple graphs.
